l. have found l -v raret'ui tests over a long period that hy using a dual Contact7 the deetruetive areing found in other terms of timers very greatly reduced. 'lhere is, @nury l, an are whenever the roller leaves one the Conducting ineniliers l' and this cannot be prevented. ln the ordinary term et timely however, there is a great deal et additional airing due to the roller lirealting Contact f irematurelv with the rouduet- :nig members lil and in mv invention this is eintirelj,T prevented. By eliminating this areing also iniproveithe timing and general p rtermanee ol' the engine to whieh the timer is attached.
